What mirror diameter gives 0.1 arc second resolution for infrared radiation of wavelength 2 micrometers?

Physics
1 answer:
Irina18 [472]2 years ago
7 0

Answer:

The diameter of mirror 5\times10^{-6}\ m

Explanation:

Given that,

Wavelength = 2 μm

Resolution = 0.1

We need to calculate the diameter of mirror

Using formula of resolution

resolution=0.25\times\dfrac{wavelength}{diameter}

diameter =0.25\times\dfrac{wavelength}{resolution}

Put the value into the formula

diameter=0.25\times\dfrac{2\times10^{-6}}{0.1}

diameter = 0.000005\ m

diameter = 5\times10^{-6}\ m

Hence, The diameter of mirror 5\times10^{-6}\ m

water has an index of refraction of 1.33. What is the critical angle for light leaving a pool of water into air? 0 37 90 49
vesna_86 [32]
When light travels from a medium with higher refractive index into a medium with lower refractive index, there is a maximum angle (called critical angle) for which all the light is reflected, so there is no refraction.

The value of the critical angle is given by:
\theta = \arcsin ( \frac{n_2}{n_1} )
when n1 is the refractive index of the first medium, while n2 is the refractive index of the second medium. In our case, n1=1.33 (the water) and n1=1.00 (the air). Putting numbers in, we get
\theta = \arcsin ( \frac{1.00}{1.33} )=49^{\circ}

A device that converts high voltages to lower voltages is a(n) ________.
AysviL [449]

Answer: A) Transformer

Explanation: A Transformer is an apparatus, device or a component in a system that is used to convert high voltage into low voltage. It is used to either increase or decrease the voltage of an alternating current.

A transformer uses the basic principle of electro magnetic induction, having two or more coils, the voltage is changed from one coil to another but with thesame frequency as alternating current energy passes through them.
